Hi splanky, I couldn't agree more regarding General Crook, and the record you selected is his very best IMO. I thought his song writing and phasing was so identifiable. As his recorded output was so slim, I am glad to get anything he did. And here's an absolute favourite composed by General, reeks of him :D, and sadly much overlooked. "Message To The World", performed by The Chi-Lites, uncredited lead vocal by Frank Reed who took over when Eugene departed to go solo. All the usual Chicago crew in attendance for this 1976 recording, produced by Marshall Thompson but most importantly arranged by Tom Tom Washington.
